Step-by-Step Solution: 6/13 + 6/12

Step 1

Find the Least Common Denominator (LCD)

The denominators 13 and 12 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 13 ร— 12 = 156.
LCD(13, 12) = 156
Step 2

Convert to Equivalent Fractions with Common Denominator 156

Multiply the numerator and denominator of 6/13 by 12, and multiply the numerator and denominator of 6/12 by 13 so both fractions share the common base 156.
6 ร— 12/13 ร— 12 = 72/156   and   6 ร— 13/12 ร— 13 = 78/156
Step 3

Add the Numerators

Now add the numerators (72 + 78 = 150) and keep the common denominator 156 unchanged.
72 + 78/156 = 150/156
Step 4
